Answers
Answer:
1/3 Part
500 litre
Step-by-step explanation:
A pipe can fill a water tank in 1 hour
1 hour = 60 mins
in 60 mins water tank is filled = 1 part
=> in 1 min water tank filled = 1/60 Part
=> in 20 mins water tank filled = 20 * 1/60 = 1/3 Part
If the capacity of the tank is 1500 litre
in 60 mins water tank is filled = 1500 litre
=> in 1 min water tank filled = 1500/60 = 25 Litre
=> in 20 mins water tank filled = 20 * 25 = 500 litre
Answer :
1) 1/3 part
2) 500 litres.
Step-by-step explanation:
capacity of the tank is 1500 litre.
It takes 60 minutes to fill the tank .
1) Part of the tank is filled by the pipe in 20 minutes :
20 minutes/ 60 minutes
=> 20/60
=> 1/3
Hence, 1/3 part of the tank is filled by the pipe in 20 minutes.
2) How many litres of water does the pipe fill in 20 minutes
60 minutes = 1500 litres.
20 minutes = (20x1500)/60
=> 30,000/60
=> 500 litres.
Hence, a pipe can fill 500 litre of water in 20 minutes
